How to get Stack size of TDI device stack?

Hello All,
Is it possible to get TDI STACKSIZE in DriverEntry? I need to get the Stack size of TDI device stack to decide at run time if i can load my driver or not? This is the requirement because of TDI stack size limitations which allows to load max. 4 driver on the stack (because of AFD.sys client limitation). So I need to know the IRP stack size, maybe in DriverEntry, to make the decision about loading of my driver at run time.

Thanks
